Definitions

  • This invention relates to an apparatus for the itemization and check out of a miscellany of items which can be operated by the customer in a self-service mode with little or no assistance from a store employee.
  • the present invention is a system for self-service checkout where the customer performs that service which would otherwise have to be performed by a store employee.
  • This system therefore, has the advantage of reducing operating costs, a savings which can be passed on to the consumer, and actively involves the customer in the checkout process.
  • Prior art devices such as those disclosed in U.S. Pat. Nos. 2,919,851 and 3,681,570 cannot prevent fraudulent substitution of higher priced goods because no means is provided for identifying the specific product.
  • the present invention overcomes this problem by incorporating the use of uniform product code identifiers into the system. Further, prior art devices are susceptible to inaccurate weighings because no provision is made for determining where weighing begins or ends.
  • the present invention provides a system of constant monitoring of item weight, individually and in the aggregate, so that at any point if the weights do not agree, an alarm is sounded and resolution is mandated.
  • the apparatus of the present invention comprises a scanning or reading means for transmitting data obtained from the uniform product code, affixed to the product, to the check out station computer which in turn communicates with a main computer; a combination screen and keyboard means for entering additional information such as specialized product codes or unscannable uniform product codes; a scale means for weighing produce; a transmitting container means for items being purchased; an optional scale means located beneath the transmitting container and upon which the transmitting container rests; a receiving container means into which items are placed after being scanned; and a scale means located beneath the receiving container means and upon which the receiving container rests.
  • the customer passes each item in succession over the scanner, and the weight, price, product name and other information relative to the product is acknowledged by the computer.
  • the cumulative weight of items then placed in the receiving container is calculated via the scale there beneath and that total is compared with the computers cumulative weight total registered item by item. If the weights do not equal, within a pre-determined tolerance level, the apparatus sounds a warning alarm.
  • a scale upon which the transmitting container is placed calculates a beginning weight total.
  • the beginning weight total must equal the cumulatively calculated total from the computer for all items and with the total weight determined by the scale beneath the receiving container. This configuration provides even greater security against fraudulent handling of items.
  • the customer having totalled his items for purchase takes the receiving container to the cashier where it is weighed a last time. This procedure insures that nothing has been added to the container after all items have been totalled.
  • FIG. 1 is a flow chart diagram illustrating the steps of use of the apparatus.
  • FIG. 2 is a side elevational view of the apparatus.
  • FIG. 1 illustrates the steps to be taken by the customer in proceeding through the checkout procedure.
  • the check out station generally at 10, is shown to have the transmitting container or cart 11 on one side, and the receiving container on cart 12 at the opposite side thereto.
  • the transmitting cart 11 is located on a weighing scale 13 (optional), and the receiving cart 12 is likewise located on a weighing scale 14.
  • the customer places the transmitting cart 11 at the end of the scanning area, opposite the receiving cart 12. From the transmitting cart 11, the customer passes an item 15 over the scanner 16 which electronically notes the price, weight, product name, and other information, and relays that information to the main computer (not shown). The item is then placed in the receiving cart 12 located upon the weighing scale 14. The main computer, having been pre-programmed with the weight of each item, feeds that information back to the check out station computer (not shown) and compares the weight of the item with the weight as calculated by the scale 14. If the weights are within a determined tolerance level, the system is clear for the scanning of the next item 15.
  • the customer After all items have been scanned and placed into the receiving container 12, the customer enters a request on the keyboard 19 for the total, and the receipt is prepared.
  • the receipt indicates the price, weight, and product name of each item, whether the item is payable by food stamps and a total weight of all items is calculated and noted.
  • the computer also assigns a transaction number which is printed on the register tape.
  • the cashier compares the weights, verifies the transaction code number and receives payment from the customer.
  • the weighing scale means 13, 14, and 17, scanner 16, and screen 18 and keyboard 19 are all in communication with the main computer.
